Experiment ZQ-29
Experiment ZQ-29 is an invisible spidersilk golem that carries some excellent treasure. There is no way to sense its presence, ESP does not work because golems have no minds, Infravision doesn't work because because golems are not living creatures that give of body heat. If you have a stethoscope you can learn that "something" has Astr 180 Lstr 180 Dex 80 Agi 80 End 0 Per 12 Int 4 Wis 4 Cha 5 Siz 250 HP 805, Hasted, Invisible, Telecontrol, Gas Immunity. If you defeat the golem you will get its spider silk armour (AV 18 +/- enchantment) a book of Sophos, a wand of cloning, scroll of change material, wand of teleportation, and wand of invisibility. The book of Sophos indicates that it has been created by either Sophos or his followers.
Note: Unlike other uniquies (or much like other golems), it does not wear or wield its equipment.
